 1. **Create a branch** for the topic you are working on.  
     Use a descriptive name:
+    
     ```
     topic-name-assignment
     topic-name-workshop
     ```
-    
 2. **Work in pairs** whenever possible. Collaborate on the content before creating a PR.
 3. **Do not merge your own PRs.** Always request a review from at least one other TA.
 4. **Specify clearly in your PR title** whether your work is for:
     - **Workshop**
     - **Assignment**
+5. **Follow conventional commits.**  
+    Use clear commit types such as:
+    ```
+    feat:, fix:, docs:, refactor:, style:, chore:
+    ```
+    Avoid vague commit messages — they make tracking work harder.
+6. **Be consistent with naming conventions.**  
+    Folder names, file names, and markdown files must follow the templates exactly.

 ## 🔹 Lectures / Workshop Content
 
 ### 1. Upload lectures to **Google Drive**
-
 - All slides and resources must be uploaded to the designated Google Drive folder for each topic.
+- **Use direct download links**, _not view links_, when referencing files inside the repo.
+
+### 📥 How to Generate a Google Drive Direct Download Link
+1. Get the file’s share link (the one ending in `.../file/d/<ID>/view`).
+2. Extract the file ID from the link.  
+    It looks like:
+    ```
+    https://drive.google.com/file/d/FILE_ID/view
+    ```
+    → The `FILE_ID` is the long string between `/d/` and `/view`.
+3. Create a direct download URL using this format:
+    ```
+    https://drive.google.com/uc?export=download&id=FILE_ID
+    ```
+4. Use **this URL** in markdown files and templates in the repo.
+

 ### 2. Create Files in the Repo
 
 For each topic, create the following files **from templates**:
+
 1. **`5-TASlides.md`**
     - Use the TA Slides template
-    - Include links to all relevant slides
+    - Include _direct download_ links to all relevant slides
 2. **`1-Workshop.md`**
     - Use the Workshop template
     - Update links to questions and slides
